Storage requirements vary depending on your deployment configuration. Different nodes and clusters can share datastores. For example, during the installation process, you can specify the same datastore forthe Compute and Image Service nodes.

For information about storage requirements per VM in a typical VMware Integrated OpenStack deployment, see Hardware Requirements.

Storage requirements vary depending on whether you deploy with NSX or VDS networking.

NSX Controller, Manager, and Edge nodes affect the storage needs in an NSX deployment.

The storage requirement calculation is based on the following nodes:

OpenStack Manager (1 node)

Load Balancers (2 nodes)

Database (3 nodes)

Memory Cache (2 nodes)

Message Queue (2 nodes)

Controllers (2 nodes)

NSX Controller (3 nodes)

NSX Manager (1 node)

Compute

20

Value is per cluster.

Each Compute cluster contains a single Compute node. To add capacity, add clusters.

NSX Edge

1.5

Value is per node.

Storage requirements for the NSX Edge cluster vary. When you create a logical subnet or router but an existing NSX Edge node cannot serve the request, an additional node is dynamically created.

Note

Creating a dedicated cluster for the NSX Edge nodes is a best practice to optimize performance. In an alternative deployment, you can include the NSX Edge nodes in the Management cluster.

DHCP nodes affect the storage needs in a VDS deployment.
